serious dangers involved. It is a necessity to keep workers safe and aware of heat stress. Overheating on

the job can lead to multiple injuries and even death.

There are many different symptoms that are related to heat stress. One can feel the body start to

profusely sweat and become clammy. You may start to feel dizzy, too-- and all of these symptoms may

occur without your awareness, which could lead you to faint and/or collapse. These symptoms may also

come with a lack of concentration, fogginess in thought, and you may feel unable to communicate


Very serious cases of heat stress can lead to stroke, dehydration, heat exhaustion, heat cramps, and / or

heat rashes. These are all very serious and require urgent medical attention to avoid further damaging

the body.

If any of these heat stress symptoms are present, it is essential to act quickly and properly. Alert a

colleague immediately. If you see someone else in duress, help the individual move to a shaded cool

area and give them water. Please seek medical attention if condition worsens.
